In the Shadow Land, apprentices are categorized into Inner Ring Apprentices and Outer Ring Apprentices.
But in the eyes of the true elites, apprentices in the Shadow Land are simply divided into Tower Inner Apprentices and Tower Outside Apprentices.
Apprentices living outside the Tower, no matter how talented or outstanding they may be, have essentially the same fate. After turning 30, they are assigned to various regions in the Dark Forest to perform different tasks—cultivating Magic Plants, raising Demons, brewing Magic Potions, and so on—laboring tirelessly in exchange for cultivation resources.
Inner Ring or Outer Ring, in the end, it's all the same. Using the class divisions of the Human World as an analogy, they all belong to the civilian class.
If the outside of the Tower represents the civilian world, then the inner Tower undoubtedly stands as the realm of Nobles!
